About Heating Oil in Maine

How much does Maine use?

Approximately 300,000 homes in Maine use heating oil as their primary heat source. The average Maine home uses about 1100 gallons per heating season (Sep–May). At today's price of $4.95/gal, that's an estimated annual heating cost of $5,445.

How to save on heating oil in Maine

The best way to save is to compare at least 3 local dealers before ordering — prices between dealers in the same area can vary 10–20 cents per gallon. Buying in the off-season (May–August) when prices are typically lowest, or signing a price cap contract in spring, can also save 15–25 cents per gallon. Set a price alert to be notified when prices drop to your target.

Where does this data come from?

Maine heating oil prices are sourced from the U.S. Energy Information Administration's weekly residential heating oil survey. The EIA surveys heating oil dealers across Maine weekly during the heating season and monthly in the off-season. City-level prices reflect the state average with small adjustments for local market conditions. Prices are updated daily on this site.
